METHODS: In our systematic review, the PubMed database was used for the literature search using the combination of words that included \"LHX6\" and \"cancer\". Relevant studies, including in vitro, in vivo experiments, and clinical studies, were analyzed in this review.
RESULTS: We found evidences that LHX6 might be important in the inhibition of tumor cell proliferation, growth, invasion, and metastasis through the suppression of Wnt/β-catenin signaling pathway. Moreover, LHX6 is observed to be downregulated in certain types of cancer due to hypermethylation, thus hindering its tumor suppressing ability. In addition, hypermethylation can also be used to determine the stage of cancer development.
CONCLUSIONS: The downregulation of LHX6 expression might be responsible in promoting cancer progression. Future studies are necessary to investigate the potential of LHX6 as a novel cancer biomarker as well as its therapeutic implications towards certain types of cancer.
